胃电是一种非侵入性记录胃肌电活动的方法。本研究的目的是用胃电方法记录新生儿的胃电活动，并比较灌胃喂养后记录的餐后胃电(胃电)的频率分布。对19名胎龄从28周到足月的婴儿进行了研究。I组只在配方奶喂养后进行研究(n=15)，按年龄分为A、B和C三个亚组：A(足月，n=4)、B(33-36周，n=4)和C(28-32周，n=7)。第II组(32~34周，n=4)分别于灌胃喂养前、后进行观察。计算胃动过缓(1~2.4cpm)、正常(2.5~3.6cpm)、胃过速(3.7~9.9cpm)、十二指肠/呼吸(10~15cpm)四个频率段胃电功率占总功率的百分比。结果显示，不同胎龄的第I组婴儿在这些频率范围内的餐后鸡蛋功率没有显著差异。在第II组婴儿灌胃喂养后，这些频率范围内的功率没有显著变化。结论：(A)早产儿和足月儿均可成功记录到胃电，(B)早产儿和足月儿各频段的餐后胃电活动相似，(C)早产儿灌胃喂养不能增加3cpm的胃电活动。
Electrogastrography is a non‐invasive method for recording gastric myoelectrical activity. The aims of this study were to record gastric myoelectrical activity in newborn infants using electrogastrographic methods and to compare frequency distributions of postprandial electrogastrograms (EGGs) recorded after gavage feedings. Nineteen infants with gestational ages ranging from 28 weeks to term were studied. Group I subjects were studied only after formula feedings (n = 15) and were divided by age into subgroups A, B and C: A (term, n = 4), B (33–36 weeks, n = 4), and C (28–32 weeks, n = 7). Group II infants (32–34 weeks, n = 4) were studied before and after gavage feeding. The percentage of total EGG power was calculated for four frequency ranges: 1–2.4 cpm (bradygastria); 2.5–3.6 cpm (normal range); 3.7–9.9 cpm (tachygastria); and 10–15 cpm (duodenal/respiratory). Results showed no significant differences in postprandial EGG power in these frequency ranges among the Group I infants of different gestational ages. The power in these EGG frequency ranges did not change significantly after gavage feedings in the Group II infants. In conclusion: (a) EGGs may be recorded successfully from preterm and term infants, (b) postprandial gastric myoelectrical activity in all frequency bands is similar among groups of premature and term infants, and (c) gavage feedings in premature infants did not increase 3 cpm EGG activity.
